Data packet header actions in fault tolerance of persistent routing sessions

In this paper the applicability of a fault tolerance synchronization algorithm is presented through data packet headers. Packet headers provide indicts for networking equipment on what must be done and in the case of real-time persistent routed sessions, these are a concise guideline on how to tune each parameter. Real-time sessions are transmitted with connection oriented protocols and need a constant communication process. Therefore, in order to provide such an ability we designed a fault tolerant algorithm and with this work, it's applicability is presented with the information fields of packet headers. Our contribution is focused on achieving reliable rerouting for real-time sessions, and the specially defined fields of type of service, flags, checksums and so on are presented with the analysis and decision making that resides in inter-networking routers.
